This invention relates to holding devices for electric devices.

An object of the invention is to improve the means for mounting electric circuit elements.

Other objects of the invention will be apparent from the following description and accompanying drawing taken in connection with the appended claim.

The invention comprises the features of construction, combination of elements, arrangement of parts, and methods oi manufacture and operation referred to above or which will be brought out and exemplified in the disclosure hereinafter set forth, including the illustrations in the drawing.

In the drawing:

Figure l is an end view of an electric cell assem-= bly and holder therefor;

Figure 2 is a side view thereof; and

Figure 3 is a section on the line 3-3 of Figure 2.

According to the invention a novel spring clip arrangement is provided which is suitable for use as a holder for potential producing cells and other electric circuit devices. The invention is particularly applicable to the mounting of small potential producing cells of the type described in J. S. Williams application Serial No. 94,793, filed August 7, 1936, now Patent No. 2,116,091, issued May 3, 1938. These cells are frequently used in radio circuits and the like for grid bias purposes.

While a preferred embodiment of the inven tion is described herein, it is contemplated that considerable variation may be made in the meth- 0d of procedure and the construction parts without departing from the spirit or the inven tion. In the following description and in the claims, parts will be identified by specific means for convenience, but they are intended to be as generic in their application to similar parts as the art will permit.

Referring to the drawing, the spring clip is shown of proportions suitable for mounting two bias cells in in series. It is obvious, however, that the dimensions of the clip can be varied to render it suitable for holding one or more cells. The cells I0 each comprise a cup-shaped metal shell electrode 9 partially or totally filled with an electrolyte II and having the electrode Q2 of opposite polarity positioned in the mouth of the shell and sealed therein by a rubber washer 13. The bottom of the outer metal shell electrode 9 is concave inward to provide a socket and disc electrode l2 has a central depression in its face to provide a second, oppositely facing socket on the other side of the cell.

The spring holding clip comprises a U-shaped wire spring id provided with loops 5 5 at the ends or" its two arms. Within each loop i5 is held a small ceramic (or other proper insulating) bushing it having a flange ii at its inner end which rests against loop it. Each bushing 16 has a central bore through which extends a wire terminal 88 having a contact head ll) formed at the inner end by heading. There is thus provided two contact heads it which oppose each other between the arms of the spring frame i l. The cells iii can be inserted between the opposed heads 69 so that one contact head iii rests in the socket depression in the bottom of the metal shell electrade 9 and the other contact head it rests in the central depression in disc electrode 32.

Ffhere more than one cell is used the cells are stacked one upon the other with the metal shell electrode S of one cell resting against the disc electrode 02 or" the adjacent cell thereby connecting the cells in series. If desired, in order to improve the contact between two adjacent cells by increasing the contact pressure, a suitable metal ball 283 may be inserted between the two cells, the ball being of such size as to exert a considerable pressure against both cells when they are assembled. It is obvious, of course, that instead of a metal ball 2E an insert of other shape 01' dimensions could be used.

Since a large amount of the assembly work for used, no extra connections being required. The 3 assembly requires no other additional support since the terminal wires 58 will support it sufficiently. If desired an insulating tubing may be placed over the assembly to prevent possible short circuits where unusual conditions are encountered.

The spring clip is very economical to manufacture and practical to use.

While the present invention, as to its objects and advantages, has been described herein as carried out in specific embodiments thereof, it is not desired to be limited thereby but it is intended to cover the invention broadly within the spirit and scope of theappended claim.

What is claimed is:

A potential cell and spring clip assembly comholding each wire terminal and a spring clip prising a potential cell assembly having a pair holding said bushings and urging them and their of opposite electrodes each having a depression associated wire terminals toward each other. therein, said depressions facing in opposite direc- 5 tions, wire terminals having heads in contact with KENNETH R, BROOKS,

said opposed electrodes, an insulating bushing JOHN W, MY,
